It depends on size and how complicated the broaching machine is. Normally, it takes 45 to 75 days to completed a machine under 8 ton. For bigger or more complicated machines, it might take 60 to 180 days.

Tool life is good when hardness of the product is under HRC 25. When hardness is above HRC 25, tool life will be reduced significantly. Broaching is not recommanded if the hardness is more than HRC 32.
